METALLIC LATHING.

4 SPECIFICATION forming part of Letters Patent No. 516,388, dated March 13,1894.

Application filed .Tune 7, 1892. Renewed January 16, 1894- Serial No. 497.108. (No model.)

To a/ZZ whom t may concern..- 4

Be it known that I, MICHAEL BRENDEL, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new yand useful Improvements in Metallic Lathing, of which the following is a specification.

This invention relates to an improved metallic lathing which is supported by metallic studding and to which the plaster coating is applied directly on each side of the same so as to form fire-proof partition walls for buildings; and the invention consists of a metallic lathing, which is made of sheet-metal of suitable thickness and bent so as to form transverse corrugations of dove-tail shape provided with straight ends and sides, and rounded o corners, said corrugated sheets being supported at the ends and at the dooropenings by upright studs of U-shaped and double ,T-shaped cross-section and at intermediate points by means of stiffening strips which are attached to the lathing by suitable fastening devices, as will be fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure'l represents a side-elevation of a partitionwall made of my improved metallic lathing. Fig. 2 is a horizontal section of the same on line 2 2, Fig. l. Fig. 3 is an elevation of a portion of the wall, drawn on a larger scale, and Fig. 4 is a vertical transverse section on line 4 4, Fig. 8.

Similar .letters of. reference indicate corresponding parts.

Referring to the drawings, A represents a section of my improved metallic lathing which is made of sheet-metal of suitable thickness,which is bent by suitable machinery into transversely-corrugated shape, the corrugations being made in dove-tail form and `provided with straight sides and ends and with rounded 0E corners as shown clearly in Fig. 4. The length of the sheet-metal employed is reduced by the bending operation to about one-third of the original length. The corrugated sections A can be readily joined in horizontal as well as vertical direction by overlapping the adjacent portions of the sections no special fastening devices being required for this purpose. The lathing A is supported on the main walls of the building by means of U -shaped studs or supports B and at the points where the doors are arranged by means of double T-shaped supports B', which latter also s erve forreceiving the door-casing. At lntermedlate points of the lathing, it is stiened or reinforced by means of vertical strips C Winch extend transversely across the corrugations and are attached to the same either by means of screw-bolts and nuts d which connect the strips C with the straight ends of the corrugations or by means of wedge-shaped anchors d having T-shaped heads which are passed through transverse slots of the supporting strips C into the narrow space between two corrugations and then turned through an angle of ninetyv degrees, so that the inner Wedge-shaped portion engages the inclined sides or throat of the corrugations,

as shown in Fig. 4.

The advantages of my improved metallic lathing are, first, that the same can be made up in sections of uniform size and applled directly so as to form a Wall by jolnlng the sections in horizontal as well as vertical d1- rection by simply overlapping one or more adjacent corrugations of the same; secondly, that the same can be used directly for partition-walls, as the plaster can be readily applied to both sides of the lathing, those portions of the plaster which enter into the narrower ends of the throats of the corrugations forming anchors for retaining the plaster 1n position, and thirdly, that a light, strong and tire-proof construction of partition-walls 1s obtained, which is specially adapted for the partition walls of tire-proof buildings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of flanged metallic studding, sections of sheet-metal lathing having dove tailed corrugations correspondlng 1n depth with the recesses formed by the inner and outer iianges of said studding, the corrugated edges of said lathing being inserted freely'between said flanges, and reinforcmg strips attached to the outer face of said corrugated plate transversely of the corrugations, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

MICHAEL BRENDEL.
